                                           The Basics of Math-Made Clear

     Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of

more tricky areas. These 30 fantastic lectures are designed to provide students with an understanding of

arithmetic and to prepare them for Algebra(代数) and beyond.

     The lessons in Basic Math cover every basic aspect of arithmetic. They also look into exponents(指数), the order of operations, and square roots. In addition to learning how to perform various

mathematical operations, students discover why these operations work, how a particular mathematical

topic relates to other branches of mathematics, and how these operations can be used practically.

     Basic Math starts from the relatively easier concepts and gradually moves on to the more

troublesome ones, so as to allow for steady and sure understanding of the material by students. The

lectures offer students the chance to "make sense" of mathematical knowledge that may have seemed so

frightening. They also help students prepare for college mathematics and overcome their anxiety about

this amazing-and completely understandable-field of study.

     By the conclusion of the course, students will have improved their understanding of basic math. They

will be able to clear away the mystery(神秘性) of mathematics and face their studies with more

confidence than they ever imagined. In addition, they will strengthen their ability to accept new and

exciting mathematical challenges.

     Professor H. Siegel, honored by Kentucky Educational Television as "the best math teacher in

America," is a devoted teacher and has a gift for explaining mathematical concepts in ways that make

them seem clear and obvious. From the basic concrete ideas to the more abstract problems, he is master

in making math lectures learner-friendlier and less scary.

     With a PhD in Mathematics Education from Georgia State University, Dr. Siegel teaches mathematics

at Central Arizona College. His courses include various make-up classes and a number of lectures for

future primary school teachers.

     If the course fails to provide complete satisfaction to you, you can easily exchange it for any other

course that we offer. Or you can get your money back.
